Here is an optical illusion of motion and color perception, which might reveal if you have normal psychological concentration.
This psychological picture test shows the amazing ability of the human brain, and perhaps, after a successful outcome of the test, it will make you wonder if we perceive the world correctly or maybe our brain deceives us. What if what we see around us is a kind of illusion of perception?
Psychological Concentration Test
Look at the picture below, and you will see the blue circles move clockwise and disappear one after the other, creating an illusion of the movement of the gray hole between them.
If you concentrate your mind in the middle of the circle on the black cross, then you will see that the moving gray hole will change its color to yellow. And then, as you continue to look at the cross for 10-15 seconds, all the blue circles will disappear and there will be only one yellow circle that will keep moving in the same direction.
It is believed that if you manage to see all the blue circles disappear and only one yellow circle move, then you have normal psychological concentration.
What do you see in the optical illusion below?
